I’m in discussion about this subject on Github: [image] Issue: Upgrade file (index.php) is wrong for version 9.1.6! [ownCloud to nextCloud migration] opened by danger89 on 2017-09-13 closed by MorrisJobke on 2017-09-13 Hi, As stated on your guide for migration: https://n…

@Morgano thanks for filing the issues. The Nextcloud updater should ignore minor versions (the .5 vs .6) on migration between different products (oC to Nc), but apparently something is wrong. It might be that oC didn’t properly set the vendor on install or update, there was a bug with that. Once 10.…

A work-around from this blog is to set the version of your ownCloud server to 9.1.5.1, see: https://0xstubs.org/migrating-from-owncloud-9-1-6-to-nextcloud-10/ edit your config/config.php and set version to 9.1.5.1 or lower.

From @nickvergessen - if the reason is that oC didn’t set the vendor properly, you should run this before you try to upgrade to Nextcloud: occ config:app:set --value "owncloud" core vendor

[image] jospoortvliet: edit your config/config.php and set version to 9.1.5.1 or lower. Reading from posts earlier in this thread, and other places, I am told that OC 9.1.6 use a newer engine than OC 9.1.5 and NC 10.0.5, so that is not a safe path anyhow. Or is there news on that? It do see…

Many thanks :slight_smile: If the workaround is safe, it will save a lot of people some work.

In my case, I had to set version 9.1.5.1 in file version.php. When I set config/config.php, the updater still recognize installed owncloud version as 9.1.6. In the end, migration from owncloud 9.1.6 (faking it as a 9.1.5.1 version) to nextcloud 10 to nextcloud 11 went well.

FYI - https://github.com/nextcloud/owncloud-web-migrator/issues/1 I modified version.php to refer to 9.1.5.1 which worked for me but didn’t work for a user on twitter. We have to fix the migration script… The upgrade itself, if you manually replace the files that is, does work.

Thanks, jospoortvliet I see you fixed the migration information :smiley: [image] Issue: Migration instruction fools admins to upgrade to incompatible owncloud before migration opened by linucksrox on 2017-06-15 closed by jospoortvliet on 2017-06-20 @Espina2 I believe #4…
